I need to disagree with the last contribution. The Babylonian names for the Julian/Gregorian months have always been used in the Levant and Iraq, and the Roman names have always been used in Egypt and North Africa. You will find both in authors of the Abbasid period, if not earlier.

As far as I know, Egypt and Gulf countries (a part from Saudi who uses Hijri calendar) use yanayer, febrayar, mars, abril, mayo, younyou, youlyou etc
Morocco uses berber name for months, Algeria and Tunisia, the French names

So there is no MSA for the months?

Actually there is something funny, my Moroccan friend always though that the months used in Morocco are classical Arabic because in oral they use the French names and writing the berber names.
I told him in classic we say Aghustus for August he was very surprised

I think we have had this discussion before. I argued that there is no such thing as “standard” Modern Arabic, given, among other things, local variations in vocabulary, as in this case.

The names for the Julian (now: Gregorian) months have a long history in Arabic. The forms used in Egypt (yanāyir etc.) go back to the mediaeval Greek pronunciation of the Latin month names. The traditional names in North Arfrica (e.g. shutamber) go back to Visigothic Latin. The modern Maghribi names (e.g. zhanfī) are French. And, as mentioned, the names used in Syria, Palestine, Iraq etc. (nisān etc.) are the Syriac names for the Julian months, which go back to the ancient Babylonian names for the roughly corresponding lunar months.

Comprehensive list:
-Saudi Arabia is the only country which uses the Hijri calendar as it's official calendar - most (all?) other Arab countries use it alongside the Gregorian calendar.
- Gaddafi had invented his own (mad) names for the Gregorian months and banned other names in Libya. After the 17 Feb revolution the Libyans adopted the Egyptian names (since they're the most common).

The naming convention which is considered official Standard Arabic, used in that country's government, media, education, etc., is summed up in this table (very carefully compiled to contain no spelling mistakes):

*** Note: The form in brackets is occasionally used in Egypt and the Sudan

You might be interested to know that all of these names (except, of course, for the French-based ones in the third column) can be found already in al-Bīrūnī الآثار الباقية عن القرون الخالية written in AD 1000.
